This platinum engagement ring belongs to the Art Deco period, circa 1930. The piece holds a bright cushion-shaped old mine cut diamond secured within four rounded claws, complemented by geometric detailing in the gallery and a slim, tapering shank. The silver-toned metal displays notched decoration at the shoulders and a polished finish. Visible elements include the cushion cut of the central diamond, the pointed claws of the setting, and the parallel line carvings along the band. The ring sits 6.0 mm from the finger with a diamond measuring 5.87 x 5.47 mm and a total weight of 3.12 grams. Intended for personal wear, the ring serves as an engagement piece or decorative jewellery suitable for everyday use.

FAQs

Art Deco rings from the 1930s typically feature geometric silhouettes, white metal settings such as platinum or white gold, and hand-cut diamonds such as old European or old cushion cuts.

Platinum and white gold were the primary metals of choice during the Art Deco era, predominantly set with diamonds, sapphires, emeralds, and rubies.

Authentic old cut diamonds feature a smaller table, steep crown angle, open culet, and hand-faceted asymmetry, typically mounted in hand-tooled settings with geometric shoulder details.

An Art Deco solitaire ring can be worn independently as a focal point, paired with a plain slim metal wedding band, or stacked alongside minimal geometric rings.

Soak the ring in warm water mixed with mild dish soap and gently clean around the setting using a soft-bristled brush, while scheduling periodic professional checks to verify claw security.
